WINDOW STAY Application filed July 20,

rIhis invention relates to easement Window adj usters or stays for opening and closing the Window, adjusting it in various positions and latching it in adjusted position. The object of the invention is to provide a generally improved Window stay. The invention is embodied in a stay comprising a notched bar secured to the WindouT and a swinging arm pivoted on the Window sill. The free end of lo the arm is adapted to engage the notches in the bar by means of a special improved latch mechanism to lock the parts in adjusted position. v

Accordingly the invention is embodied in a Window stay constructed and arranged as hereinafter set forth and as illustrated in the accompanying drawing in Which Fig. 1 is a plany view in section of a casement Window equipped With a stay embodying the invention.

Fig. 2 is a perspective view showing a portion of the notched Window bar.

Fig. 3 is a side vien7 of the latch mechanism in latched position.

Fig. 4 is a. similar View showing the parts in unlatched position.

Figs. 5, 6, 7 and 8 show detail views of parts vof the latch mechanism.

in the drawing the reference numeral 10 denotes the Window frame, 11 is the Window sill and 12 the Window pivoted at 13. No particular type of Window is shovvn because the inventionv is usable on all types of casement Windows including those With olf set hinges as it permits a complete ninety degrees opening movement as shown in dotted lines in Figure 1.

To the Window 12 there is secured a Window bar 14: having a lower guiding groove 15 and an upper guiding flange 16. The bar is cut out as atV 17, 17 and the cut out portions 18 are bent inwardly to form a plurality of notches 19, 19. To the Window sill there is secured a bracket 20 on which is pivoted at 21 an operating arm 22. At the outer end of the latter there `is pivoted an improved special latch mechanism for latching the arm to the Window bar in adjusted positions including full open and full closed positions.

As seen in Figures 3 to 8, the outer free 1928. Serial N0. 294,116.

end of the arm 22 carries apost or pivot 23. Gn the latter 1s pivoted a latch guide 24C, Fig. l, consisting of a piece of metal bent to form a horizontal base 25, an upright guide portion 26 and depending guide feet 27, 27.

rlhe base is Vprovided with tivo ears 28, 28. A pin 29 passes through the ears 28 and through the side Walls 39 of a latch housing 31'Which forms a latch 32, Fig. 8. rThe latch housing ias an oblong hole 33 through Which the pivot 23 projects. The latch 32 projects through a cut out 34: inthe upright guide portion 26. From this it vvill be understood that the latch housing 31 With the latch 32 is piv-r oted on the pin 29 in the latch guide 24:. "A spring 35 Wit-hin the housing 31 keeps the latch 324 in normal upper locked position in a notch 19 as seen in Figures 3, 5 vand 6. On

top of the latch housing 31 rests a finger piece or handle 36 Which svvings on the pivot 23 and is adapted to be tipped on said pivot by reason rof an oblong hole 37 in the finger piece.

The normal position of the latch mechanism irrespective of the position of the Window is 'as shown in Figures 1, 3, 5 and G, Where it Will be seen that the latch engages a notch 19 in the Window bar iiush With the lflanges 18. Hence relative lateral movement between the latch and the arm 22 on the one hand, and the Window on the other hand is impossible and the Window is latched. The linger piece may be swung into any convenient position in operating the Window.

When the vvindovi7 is to be moved from one position to another, the latch is'unlatched by the operator taking hold of the finger piece at the lateral angular position thereof most convenient and lifting the finger piece, thereby depressing the latch as shovvn in Figure i and disengaging it from the notch 19 to a position below the flanges 18. The vvindov7 may noW be moved by thev operator pullin@ or pushing With the finger piece in depressed position. During this movement the upright guide 26 slides along the flange 16 an-d the guide feet 27 slide in the groove 15 thus preventing any binding or catching during the movement of the Window. "W hen the desired position has been reached, the operator lets go of the linger piece and the latch then automatically snaps upward into a notch 19 under the influence of the spring 35 and the Window is then latched in a new position. Should the latch not be directly under a notch 19, a slight sliding` movement to one side or the other Will bring the latch under an adjacentnotch into which the latch Will snap and the parts are latched.

The improved Window stay as herein disclosed possesses several practical advantages. The fact that the operatingfinger piece is pivoted enables the operator to catch hold of it atthe most convenient angle for moving` the Window and While the linger piece projects suiiiciently to enable a irm grip, yet it may be placed as shown in Figure l to permit use of a screen closeto the Window. The depressing movement in disengaging the latch is also a natural movement not hindered by the Weight of the Window. rThe stay is usable for both a right and a left Window by merely swinging the arm 22 and bracket 2O around the pvot 23 to a position opposite to that shown in Figure 1 which shows it applied to a right hung Window.

I claim A Win-dow stay of the character described comprising a notched bar fastened to the Window, an operatingarm pivoted on the Window silla latch mechanism mounted on the free end of the arm and comprising guiding means adapted to guide the latch' mechanism along the bar, a latch pivoted on said guiding meansJ a spring for causing` the latch to automatically engage any one of the notches in the bar, and a finger piece laterally svvingahly mounted on the latch mechanism for actua-ting the latch to disengage it from a notch in the bar irrespective of the lateral position of said finger piece ED'WN JOHN SIBLEY.
